Shure KSM137 — Small Diaphragm Cardioid Condenser Microphone
KSM137 Overview
The Shure KSM137 is a professional small-diaphragm condenser microphone built for demanding instrument capture in live, studio, and broadcast environments. Its gold-layered Mylar diaphragm preamplifier delivers transparent, accurate reproduction across a broad range of sources, while a subsonic filter eliminates low-frequency rumble that can compromise clarity in critical recordings. An onboard pad extends the microphone’s usability to high-SPL sources without distortion. The KSM137 is well suited for audio engineers, live sound professionals, and studio operators who require consistent, reliable performance on acoustic instruments, choirs, and drum overheads.
The cardioid polar pattern provides focused sound isolation, making the KSM137 effective in complex stage and studio environments where rejection of off-axis sources is essential.
